I cannot believe all the response I got!
Going through the response, I think I found a solution. I increased the Caustic Blur to 1 and that did the trick. I'm attaching the new renders here. I also reduced the glossy depth and diffuse depth further. Thank you for all your help!
I do have some further questions if that's ok.
1) Does enabling "Allow Caustics" increase render cost for an engine like Octane?
2) And I know that this is a very scene dependent value, but would this light bright be considered bright enough? This is how I'm lighting this scene
Thank you again for all your answers!

Tim
